This proposal describes the effort required to take the results of the Phase I Real Time Airborne Particulate Detector feasibility work through the R&D phase. The Phase II prototype airborne sensor will operate in either of two modes; on a stand-alone basis as a particulate sensor and data logger, or as a sensor operating with a portable computer to permit real time data analysis and to allow graphic or tabular displays of on-going measurements. The attached work plan includes development of product performance requirements based on user needs; generation of preliminary product specifications and drawings; the remaining effort needed to design. build, test. and analyze the performance of prototype hardware; and to prepare a preliminary cost estimate for production hardware. Completion of this Phase II work will provide the essential technical data necessary to begin the Phase III commercialization. The basic objective of this work is the development of a portable instrument which measures and records airborne particulate data in real time. at a very low cost. The instrument is intended to augment not replace. larger, more expensive, and possibly more accurate instruments such as the Dichot and TEOM which are currently in use.Applications:Development of product requirements. followed by design/test/evaluation in the lab and the field are expected to provide a product with benefits for environmental regulators, researchers, and users. The regulator will have better data to assess the true environmental status and potential impact of ongoing field operations al a point in time. Researchers and users will be able to obtain real time data to accurately assess particulate generators and abatement methods while operations are underway. Affordability and real time results will provide a means whereby new methods to improve our environment and reduce unnecessary risks can be accuratelv assessed.
